Abstract

All in-plane aligned a-axis oriented YBa₂Cu₃O_x/Gd₂CuO ₄/YBa₂Cu₃O_x superconductor/insulator/superconductor (SIS) junction structures are fabricated by a pulsed laser deposition technique and their microstructures are characterized. An insulating barrier of Gd₂CuO₄ with an atomic graphoepitaxial relation is selected from a lattice-matching point of view for the b-and c-axes of YBa₂Cu₃O_x at a deposition temperature of the YBa₂Cu₃O_x films. Preferred orientations and in-plane alignments of electrodes of YBa₂Cu₃O_x films and barriers of Gd₂CuO₄ films are confirmed by X-ray diffraction spectroscopy and an X-ray φ-scan technique. X-ray diffraction measurements revealed that all the YBa₂Cu₃O_x/Gd₂CuO ₄/YBa₂Cu₃O_x films are a-axis oriented. The c-axes of the layers are also in-plane aligned.
